A post on the Alan Wake Community Forums from Remedy announces that their decision to belatedly bring Alan Wake to the PC has resulted in the game hitting #1 on Steam and making back their investment in porting the psychological thriller to Windows (thanks Eurogamer).

I wanted to chime in here. We are very happy with the sales and hitting #1 on Steam at launch was nothing short of amazing. We recouped our development and marketing expenses during the first 48 hours. And yes, we're certainly very excited about PC.
